摘要:
The present invention relates to holographic multicolor optical elements for use as multicolor filters in liquid crystal displays and methods of making the elements. The elements can be used as multicolor reflective or transmission filters The elements can have one, two, three or more holographic recording film layers Each layer comprises at least first and second pixel volumes containing holographic mirrors and preferably third pixel volumes containing a holographic mirror.

The present invention relates to a process for forming an organic electronic device having at least two organic layers. The process includes (a) applying a first organic layer having a first organic material by a method selected from vapor deposition and liquid deposition from a first organic liquid medium; (b) applying a second organic layer having a photoactive compound directly over at least a portion of the first organic layer by liquid deposition from a second organic liquid medium, wherein the first organic material is sparingly soluble in the second organic liquid medium.
摘要:
A diffuse reflective article is provided including a diffuse reflector of light positioned within a structure defining an optical cavity. The diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension. Also provided is an optical display, including: (i) a structure defining an optical cavity; (ii) a light source positioned within the optical cavity; (iii) a display panel through which light from the light source passes; and (iv) a diffuse reflector positioned within the optical cavity for reflecting light from the light source toward the display panel, wherein the diffuse reflector is a nonwoven sheet containing a plurality of inter-fiber and intra-fiber pores of optimal light scattering dimension.

This invention relates to diffuse reflectors of visible light comprising a nonwoven sheet having on at least one face thereof a binder layer comprising a binder and a scatterer of visible light dispersed in the binder. These diffuse reflectors have utility in light management in optical displays such as backlit LCD displays for lap top computers and televisions.

A reflective liquid crystal display contains, a holographic reflector that provides either a white or more neutral background color to the display when viewed with ambient white light. The holographic reflector comprises a holographic recording film layer that includes at least first and second pixel volumes containing holographic mirrors and, preferably, third pixel volumes containing holographic mirrors.
